Reaching out to fellow Reduser electronic gurus.
I need help figuring out how to avoid flickering when using EPIC Dragon with my 35mm film scanner.
For the illumination I'm using a 50W Yuji Led chip (5600K version) https://store.yujiintl.com/collections/frontpage/products/bc-series-cob-400l and it is powered using this PSU https://www.amazon.com/gp/product/B01N374QPE/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=13
The issue is that there are scan bars slowly moving down in my scans when shooting at shutter speeds other than 1/60th. It's like a darker horizontal band taking about 1/4th of the screen and you can see it moving when playing back a scanned clips.
It sucks because I could REALLY use HDR in this application but with HDRX set to 1/60th for A Frame, then the X frame track has flicker issue.
Any suggestions on how to improve my LED power or other power supply recommendations, so I could use more shutter speeds (HDRX) and not have to worry about scan bars / flicker ?
Someone suggested I install a High Speed Dimmer between the power supply and the LED Chip similar to this and said it would improve flickering. What do you guys think?
